摘要： The invention provides a method and apparatus for providing hitless protection switching in a synchronous transmission system. A switching apparatus is arranged to receive data signals on at least two transmission paths and to output data from a selected one of said transmission paths. The apparatus is arranged to align the respective received data signals so that a selector mechanism can select between corresponding elements of the received data signals. This arrangement allows hitless switching to be performed since there is no loss or repetition of signal elements when switching occurs. In a preferred embodiment, data in respect of each frame of each data signal is stored and the selector mechanism selects between paths on a frame-by-frame basis by comparing quality information carried by the data signals. This arrangement offers a very low end to end Bit Error Rate (BER) performance.

摘要： The invention concerns a switching apparatus comprising a low order switch subtended from a high order switch. In order to compensate for delays incurred by passing a data frame through the high order switch to the low order switch and delays incurred by the operation of the low order switch, the apparatus is arranged to advance the payload of a received data frame with respect to the fixed overhead of the data frame by an amount corresponding to the incurred delays. The low order switch uses the advanced payload to create an output frame, for sending to the high order switch, which is advanced with respect to the data frame that it receives. The apparatus, which is particularly suitable for use in SDH and/or SONET systems, obviates the need to provide an alignment apparatus, such as a VT/TU aligner between the high order switch and the subtended low order switch.

摘要： It is often required to send a plurality of streams of data in parallel between two network nodes in a synchronous transmission network and also to maintain a particular alignment between those streams of data. This is particularly required when the streams of data are to be transmitted over a wide area network, for example, for data mirroring applications. Virtual concatenation is used for each of the individual data streams as known in the art and in addition, the individual virtual concatenation processes are synchronized or co-ordinated. At a destination node it is then possible to realign the individual data streams with respect to one another.

摘要： A method and apparatus that allows egress pointer smoothing data by evaluating the average fill of an elastic store. For one embodiment of the invention, by measuring the average fill, the 3 bytes of SOH and 87 bytes of data are taken together in each sample, and the relative phase of ingress and egress frames does not impact the fill depth calculation. For one such embodiment, the calculation is performed by summing the elastic store fill over a full row and increment/decrement decisions based on that average figure provide smooth rate of pointers coming out even as a section overhead moves through the frame.

摘要： An apparatus for monitoring a path or section trace identifier. The apparatus receives the trace identifier and subjects it to a transform algorithm to produce a transformed trace identifier. The apparatus then compares the transformed trace identifier with a correspondingly transformed expected trace identifier and determines if there is a match or a mismatch. The CRC-32 (32-bit cyclic redundancy check) checksum algorithm may be used. The algorithm produces transformed trace identifiers that are significantly smaller than the non-transformed trace identifiers.

摘要： One aspect of the invention provides an apparatus for modelling a plurality of switching operations arranged in a plurality of switching stages. The apparatus comprises a respective switch stage component for each switching stage, and each switch stage component comprises a respective addressable switch state indicator for each switching operation associated with the respective switching stage. The values of the switch state indicators in a given switch stage component identify a respective switch state indicator in another switch stage component. The switch stage components are interconnected such that addressing a switch state indicator in one switch stage component causes the respective identified switch state indicator in another switch stage component to be addressed. In the preferred embodiment, each switch stage component comprises a respective Look-Up Table.

摘要： A method and apparatus that allows egress pointer smoothing data by evaluating the average fill of an elastic store. For one embodiment of the invention, an elastic store implements a plurality of independent FIFOs, each FIFO having a write pointer and a read pointer, the write pointer including a marking pointer field and valid flag field. An incoming byte is received to a location within a traffic memory and the write pointer is used to instruct the traffic memory to indicate that the incoming bit has been received to the location. The valid flag field is set to indicate that the value at the location is currently valid.
